My own experience disagrees. I spent 17 months bringing up a Xeon-D based traffic shaper for 40Gb/s of traffic in a radio base station. And yes, when collected crunched traffic statistics, it did use more than 4GB of address space to do so. > On Mar 30, 2023, at 5:30 PM, Elliott Mitchell

[PATCH 6/9] kernel/x86: enable x32 support for amd64

2023-04-26 Thread Elliott Mitchell
Full amd64 support isn't really appropriate for most situations OpenWRT is deployed. Whereas x86-x32 seems extremely appropriate for these situations. As such enable x86-x32 support. CONFIG_ARCH_MMAP_RND_COMPAT_BITS is required to follow along, otherwise the kernel build breaks. Signed-off-by:
